Haplogroup I-BY2776

What is Paternal Haplogroup I-BY2776?

Haplogroup I-BY2776 is a group of Y-chromosome lineages defined by unique genetic markers. Your paternal haplogroup, or that of your father if you do not have a Y-chromosome, sheds light on the migrations of your ancestors. Although your paternal haplogroup reflects just one of your many ancestral lineages, it carries information about that lineage over tens of thousands of years.

Haplogroup I-BY2776 is descended from haplogroup I-BY433. Among 23andMe research participants, haplogroup I-BY2776 is commonly found among populations in the United Kingdom and Ireland.

It's important to note that your haplogroup doesn't define your current ethnic identity; rather, it provides an insight into your deep ancestry on the paternal side.
